Serial connection

[Gennadiy]

Hi!
I apologize for my poor knowledge of English. I want to develop a vocal processor.
I wanted to use the Mixer Application (http://www.spinsemi.com/mixer_application.html) as a base. But connect several modules in series so that you can use several effects at the same time. The first module is for echo (switched on by the pedal), then the chorus module (switched on by the second pedal), and then the reverb module.
1. Is it possible to connect three boards with FV-1 in this way? Will the sound quality degrade a lot?
2. The program tab goes to the Mixer Application. Do these programs need to be loaded into separate memory? Or are these programs that are inside FV-1 and they do not need separate memory?
3. Can I use these programs if I sell this vocal processor?
Thanks!

Depending on some things in each code, you can put them together in the same program, use a skip routine to select which one is active (you'll loose a pot but maybe is not that big deal)

Thanks! I thought about it. But if you want all three effects to work simultaneously, then you need three FV-1s. Since the settings for each effect are different.

They must be loaded into the external EEPROM

Yes but you must give credit to Spin in documentation and on your website like "This product uses programs provided by Spin Semiconductor" or similar

Frank, thanks!
Does anyone have any information on the first question? Have you tried connecting several FV-1s in series?

Yes..You can connect FV-1 DSP's in series or parallel. For your purpose I would consider just 2 FV-1 chips as 2 of the effects can easily be programmed on 1 FV-1 and give enough pot controls but it really depends on how many pots per effect you want in the digital domain. Some of your control post could be analogue rather than through the DSP. So it really depends on how you design the rest of your circuit.

Understood thanks!
Somehow I did not immediately think about two effects on one processor.
